IiEE W. BARBER AND EDWIN W. WEBB,. 0F CHICAGO, ILLINOIS, ASSIGNORS TO STANDARD CAR TRUCK COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION 0F NEW JERSEY.

Application tiled June 6,

vTo all whomzt may concern:

Be it known that we, LEE W. BARBER and EDWIN WEBB, citizens of the United States, residing at Chicago,I in the county of Cook and State ofl Illinois, have invented certain new and useful Improvements in Side Bearings ;`and we do hereby declare the following to be a full, clear, and exact description'of the invention, such as will ena ble others skilled in the art to which it appertains to make and use the same.

This invention relates to a bearing for railway cars and particularly to a side beari ling adapted to be disposed between the truck and body bolsters of such a car.

It is an object of this invention to simplifythejstructure of such a bearing and to provide one form of the same comprising only three parts, a housing, a bearing plate and a roller. ltsis a further object of the invention to provide the bearing roller with integral means for locking the same to the housing and also to provide improved means .for retaining the bearing plate in the housing.

These and otherv objects and advantages of the invention will be apparent from the following description made in connection with the accompanying drawings, in which like reference characters refer to the same parts throughout the different views, and in which Fig. 1 is a top plan view of the bearing assembled;

Fig. 2 is a view in side elevation of the same, a portion thereof being shown in section and different positions of the roller belng indicated by dotted lines;

vFig. 3 is a verticalcentral section of such a bearing;

Fig. 4 is a partial top plan View of the bearing plate; and

Fig. 5 is a. section of a modified form of the roller.

Referring to the drawings, the bearing as a whole comprises a housing member a, a bearin plate b anda roller c. The housing a iso substantially rectangular form and comprises substantially parallel side walls connected by webs at each end forming the end Walls of the housing which webs are -curvedinwardly on a curve having a radius substantially the same as the bearing roller. It will be noted that the said webs are prosIDE BEARING.

1921. serial No. 475,395.

vided with openings below the top portion lthereof and that side webs al extend from the top of said webs at each side thereof to the base portion of the housing. At one side the housing is provided with a projecting portion in which is formed a recess or slot a2, the top of whichas will be seen from Fig. 2, slopes downwardly toward the center of the housing at an incline 'substantially the same as that of the surface of the bearing plate to be later described. The

recess a2 extends toward each end of the posed in the housing with its bottom surface flush with the bottom surface of the housing and is provided on its top surface with downwardly inclined bearing surfaces converging toward the center of the housing, the ends of the plate being beveled downwardly and outwardly, as clearly shown in Fig. 2. The plate is formed at each end with a central notch b1, the inner edge of which is inclined is' formed on one side with a projecting longitudinally extending lug' b2 adapted yto be received in the recess a2 of the housing.

downwardly and inwardly and the plate It will be noted that the end walls of the housing are inclined outwardly and downwardly at a and the bearing plate b is arranged to be inserted into the housing from below. The lugs a5 will then enter the notches Z1* and are adapted to be then bent inwardly adjacent the inclined surfaces of the notches so that the plate is 'held from dropping from the housing and the same will also be prevented from rising by contact with the end portions 1L of the housing. The bearing plate is preferably made of hardened lsteel and will 'preferably be a steel casting although the same might also be forged. The'bearing ,plate is suitably cored and ribbed on its undersurface, as shown in Figs. 3 and 4. f

rFhe roller c is of general cylindrical shape and rolls on top of the bearing plate b with its ends parallel and in close proximity to the undersurface of the side walls of the housing. The roller is suitably cored to eliminate excessive weight and in accordance with this invention, the same is provided with a central projecting hub c1 adapted to be disposed in the recess a2 of the housing.

The roller is made to run in close contact with the side walls of the housing so as to get all Apossible wearing. surface on the bearing plate b, and by having one side of the housing formed with a continuous unbroken surface, an increased bearing and wearing surface for that end of the roller is obtained. `When the roller is moving in operation the projection 01 will move into the ends of the recess a2 as the roller travels to one end or the other of the housing, and the travel of the roller is limited by the saine striking the end walls of the housing. The roller returns to its central position by gravity on account of the inclined surface of the bearing plate Z) and the same is locked in the housing or prevented from rising therefrom by the engagement of the hub or projection c1 with the top of the recess a2.

ln F ig. 5, a slightly modified form of roller is shown in which the roller d is provided with a central core, as in the other drawings, but is bored at each end to receive a separate pin ll which is preferably welded to the roller or has to be substantially integral therewith, this preferably being done by spot welding with acetylene.

In assembling the device the roller is dropped into the housing Vfrom the bottom with the hub c1 in the recess a2 is then inserted in the bottom and the lugs a5 bent into contact therewith.

The operation of the device has already been indicated and it is thought will be clearly understood. It will be noted that the hub or projection c1 does not bear on the housing when the roller travels on the bearing plate but merely comes into contact titl and easily assembled and require with the top of the ledge in the recess a2 when the roller tends to lift.

It will thus be seen that applicant has provided an extremely simple and efficient side bearing and one comprising very few parts. These parts can be ruggedly made no separable fastenings for holding the same in assembled position. e

It will, of course, be understood, that various changes may be made in the form, details and arrangement of the device without departing from the scope of applicants invention, which, generally stated, consists in the matter shown and described and set forth in the appended claims.

What is claimed is:

l. A side bearing for railway cars having in combination, a housing having inside and the plate walls with inside flat substantially parallel surfaces, a bearing plate in the bottom of said housing, a bearing roller supported on said plate, said roller having one end formed as an uninterrupted plane surface arranged to bear against the wall of the housing, and means on the other end of the roller co-operating with the housing to prevent the roller lifting therefrom.

2. A side bearing forrailway cars having in combination a housing having substantially straight vertical parallelside walls and curved end walls, one of said walls hav-A ing a substantially T-shaped recess formed therein the upper arms thereof extending toward each end thereof and entirely closed at the top, a bearing plate secured in said housing and a substantially cylindrical roller disposed in said housing having one plane uninterrupted end'surface adapted to bear against one side wall .of said housing supported upon said plate and having a central projecting hub at its other end adapted to travel in said recess whereby said roller is prevented from rising from the housing.
